Context / Contexte

CERFACS develops all models and tools to perform Large Eddy
Simulations (LES) of reacting flows in combustion chambers.
The AVBP code of CERFACS (www.cerfacs.fr/cfd/parallel.php)
is the official tool of the SAFRAN group and is used widely
in France and Europe for LES of reacting flows. The main application
today is the prediction of combustion oscillations which can
lead to the loss of the turbine and of the aircraft or
helicopter. Only LES has the capability to predict these
phenomena. Thermo-acoustic instabilities are a recurrent problem
limiting the range of operation of the aeronautical and power
generation gas turbine engines.
Prediction of their appearance at the design stage is very
difficult or even impossible today. The numerical approach that
is Large Eddy Simulations (LES) is in this context very promising
 and recent applications prove the power of this new numerical tool.

Description / Description

For this internship, the use of LES will be continued in collaboration
with the SAFRAN group to assess its predictability for real gas turbine
geometries operated at various conditions. The trainee will learn LES with
 the CERFACS researchers and apply it to various academic
cases and later to real configurations provided by SNECMA,
TURBOMECA or ALSTOM.
This training time can be extended to a full PhD program in Touloue (3 years).
